There is no competition. Not when Apple rakes in the lion's share of the profits.Apple is having real competition.
They "don't care" because outside of a few tech nerds most of Apple's customers are comfortable with what Apple offers and don't feel the need to micromanage the kernal level of their phones to get alt app stores that they never go to. They want to turn it on, take some photos, use a few apps and make some calls and play a game or two.Apple only success is their uber loyal faithful who don’t care.
The simplicity of iOS & the iPhone (despite the bungling and attempts to tear it down by the EU Cabal) is the key to the success of the iPhone and, as you put it, their "uber loyal faithful".
